  text: Quantum entanglement is a key resource in currently developed quantum technologies.
    Sharing this fragile property between superconducting microwave circuits and optical
    or atomic systems would enable new functionalities, but this has been hindered
    by an energy scale mismatch of >104 and the resulting mutually imposed loss and
    noise. In this work, we created and verified entanglement between microwave and
    optical fields in a millikelvin environment. Using an optically pulsed superconducting
    electro-optical device, we show entanglement between propagating microwave and
    optical fields in the continuous variable domain. This achievement not only paves
    the way for entanglement between superconducting circuits and telecom wavelength
    light, but also has wide-ranging implications for hybrid quantum networks in the
    context of modularization, scaling, sensing, and cross-platform verification.

  text: Currently available quantum processors are dominated by noise, which severely
    limits their applicability and motivates the search for new physical qubit encodings.
    In this work, we introduce the inductively shunted transmon, a weakly flux-tunable
    superconducting qubit that offers charge offset protection for all levels and
    a 20-fold reduction in flux dispersion compared to the state-of-the-art resulting
    in a constant coherence over a full flux quantum. The parabolic confinement provided
    by the inductive shunt as well as the linearity of the geometric superinductor
    facilitates a high-power readout that resolves quantum jumps with a fidelity and
    QND-ness of >90% and without the need for a Josephson parametric amplifier. Moreover,
    the device reveals quantum tunneling physics between the two prepared fluxon ground
    states with a measured average decay time of up to 3.5 h. In the future, fast
    time-domain control of the transition matrix elements could offer a new path forward
    to also achieve full qubit control in the decay-protected fluxon basis.

  text: "About a 100 years ago, we discovered that our universe is inherently noisy,
    that is, measuring any physical quantity with a precision beyond a certain point
    is not possible because of an omnipresent inherent noise. We call this - the quantum
    noise. Certain physical processes allow this quantum noise to get correlated in
    conjugate physical variables. These quantum correlations can be used to go beyond
    the potential of our inherently noisy universe and obtain a quantum advantage
    over the classical applications. \r\n\r\nQuantum noise being inherent also means
    that, at the fundamental level, the physical quantities are not well defined and
    therefore, objects can stay in multiple states at the same time. For example,
    the position of a particle not being well defined means that the particle is in
    multiple positions at the same time. About 4 decades ago, we started exploring
    the possibility of using objects which can be in multiple states at the same time
    to increase the dimensionality in computation. Thus, the field of quantum computing
    was born. We discovered that using quantum entanglement, a property closely related
    to quantum correlations, can be used to speed up computation of certain problems,
    such as factorisation of large numbers, faster than any known classical algorithm.
    Thus began the pursuit to make quantum computers a reality. \r\n\r\nTill date,
    we have explored quantum control over many physical systems including photons,
    spins, atoms, ions and even simple circuits made up of superconducting material.
    However, there persists one ubiquitous theme. The more readily a system interacts
    with an external field or matter, the more easily we can control it. But this
    also means that such a system can easily interact with a noisy environment and
    quickly lose its coherence. Consequently, such systems like electron spins need
    to be protected from the environment to ensure the longevity of their coherence.
    Other systems like nuclear spins are naturally protected as they do not interact
    easily with the environment. But, due to the same reason, it is harder to interact
    with such systems. \r\n\r\nAfter decades of experimentation with various systems,
    we are convinced that no one type of quantum system would be the best for all
    the quantum applications. We would need hybrid systems which are all interconnected
    - much like the current internet where all sorts of devices can all talk to each
    other - but now for quantum devices. A quantum internet. \r\n\r\nOptical photons
    are the best contenders to carry information for the quantum internet. They can
    carry quantum information cheaply and without much loss - the same reasons which
    has made them the backbone of our current internet. Following this direction,
    many systems, like trapped ions, have already demonstrated successful quantum
    links over a large distances using optical photons. However, some of the most
    promising contenders for quantum computing which are based on microwave frequencies
    have been left behind. This is because high energy optical photons can adversely
    affect fragile low-energy microwave systems. \r\n\r\nIn this thesis, we present
    substantial progress on this missing quantum link between microwave and optics
    using electrooptical nonlinearities in lithium niobate. The nonlinearities are
    enhanced by using resonant cavities for all the involved modes leading to observation
    of strong direct coupling between optical and microwave frequencies. With this
    strong coupling we are not only able to achieve almost 100\\% internal conversion
    efficiency with low added noise, thus presenting a quantum-enabled transducer,
    but also we are able to observe novel effects such as cooling of a microwave mode
    using optics. The strong coupling regime also leads to direct observation of dynamical
    backaction effect between microwave and optical frequencies which are studied
    in detail here. Finally, we also report first observation of microwave-optics
    entanglement in form of two-mode squeezed vacuum squeezed 0.7dB below vacuum level.
    \r\nWith this new bridge between microwave and optics, the microwave-based quantum
    technologies can finally be a part of a quantum network which is based on optical
    photons - putting us one step closer to a future with quantum internet. "

  text: "About a 100 years ago, we discovered that our universe is inherently noisy,
    that is, measuring any physical quantity with a precision beyond a certain point
    is not possible because of an omnipresent inherent noise. We call this - the quantum
    noise. Certain physical processes allow this quantum noise to get correlated in
    conjugate physical variables. These quantum correlations can be used to go beyond
    the potential of our inherently noisy universe and obtain a quantum advantage
    over the classical applications. \r\n\r\nQuantum noise being inherent also means
    that, at the fundamental level, the physical quantities are not well defined and
    therefore, objects can stay in multiple states at the same time. For example,
    the position of a particle not being well defined means that the particle is in
    multiple positions at the same time. About 4 decades ago, we started exploring
    the possibility of using objects which can be in multiple states at the same time
    to increase the dimensionality in computation. Thus, the field of quantum computing
    was born. We discovered that using quantum entanglement, a property closely related
    to quantum correlations, can be used to speed up computation of certain problems,
    such as factorisation of large numbers, faster than any known classical algorithm.
    Thus began the pursuit to make quantum computers a reality. \r\n\r\nTill date,
    we have explored quantum control over many physical systems including photons,
    spins, atoms, ions and even simple circuits made up of superconducting material.
    However, there persists one ubiquitous theme. The more readily a system interacts
    with an external field or matter, the more easily we can control it. But this
    also means that such a system can easily interact with a noisy environment and
    quickly lose its coherence. Consequently, such systems like electron spins need
    to be protected from the environment to ensure the longevity of their coherence.
    Other systems like nuclear spins are naturally protected as they do not interact
    easily with the environment. But, due to the same reason, it is harder to interact
    with such systems. \r\n\r\nAfter decades of experimentation with various systems,
    we are convinced that no one type of quantum system would be the best for all
    the quantum applications. We would need hybrid systems which are all interconnected
    - much like the current internet where all sorts of devices can all talk to each
    other - but now for quantum devices. A quantum internet. \r\n\r\nOptical photons
    are the best contenders to carry information for the quantum internet. They can
    carry quantum information cheaply and without much loss - the same reasons which
    has made them the backbone of our current internet. Following this direction,
    many systems, like trapped ions, have already demonstrated successful quantum
    links over a large distances using optical photons. However, some of the most
    promising contenders for quantum computing which are based on microwave frequencies
    have been left behind. This is because high energy optical photons can adversely
    affect fragile low-energy microwave systems. \r\n\r\nIn this thesis, we present
    substantial progress on this missing quantum link between microwave and optics
    using electrooptical nonlinearities in lithium niobate. The nonlinearities are
    enhanced by using resonant cavities for all the involved modes leading to observation
    of strong direct coupling between optical and microwave frequencies. With this
    strong coupling we are not only able to achieve almost 100\\% internal conversion
    efficiency with low added noise, thus presenting a quantum-enabled transducer,
    but also we are able to observe novel effects such as cooling of a microwave mode
    using optics. The strong coupling regime also leads to direct observation of dynamical
    backaction effect between microwave and optical frequencies which are studied
    in detail here. Finally, we also report first observation of microwave-optics
    entanglement in form of two-mode squeezed vacuum squeezed 0.7dB below vacuum level.
    \r\nWith this new bridge between microwave and optics, the microwave-based quantum
    technologies can finally be a part of a quantum network which is based on optical
    photons - putting us one step closer to a future with quantum internet. "

  text: Traditional optical elements and conventional metasurfaces obey shift-invariance
    in the paraxial regime. For imaging systems obeying paraxial shift-invariance,
    a small shift in input angle causes a corresponding shift in the sensor image.
    Shift-invariance has deep implications for the design and functionality of optical
    devices, such as the necessity of free space between components (as in compound
    objectives made of several curved surfaces). We present a method for nanophotonic
    inverse design of compact imaging systems whose resolution is not constrained
    by paraxial shift-invariance. Our method is end-to-end, in that it integrates
    density-based full-Maxwell topology optimization with a fully iterative elastic-net
    reconstruction algorithm. By the design of nanophotonic structures that scatter
    light in a non-shift-invariant manner, our optimized nanophotonic imaging system
    overcomes the limitations of paraxial shift-invariance, achieving accurate, noise-robust
    image reconstruction beyond shift-invariant resolution.

  text: "Flatbands have become a cornerstone of contemporary condensed-matter physics\r\nand
    photonics. In electronics, flatbands entail comparable energy bandwidth and\r\nCoulomb
    interaction, leading to correlated phenomena such as the fractional\r\nquantum
    Hall effect and recently those in magic-angle systems. In photonics, they\r\nenable
    properties including slow light1 and lasing2. Notably, flatbands support\r\nsupercollimation—diffractionless
    wavepacket propagation—in both systems3,4.\r\nDespite these intense parallel efforts,
    flatbands have never been shown to affect the\r\ncore interaction between free
    electrons and photons. Their interaction, pivotal for\r\nfree-electron lasers5,
    microscopy and spectroscopy6,7, and particle accelerators8,9,\r\nis, in fact,
    limited by a dimensionality mismatch between localized electrons and\r\nextended
    photons. Here we reveal theoretically that photonic flatbands can overcome\r\nthis
    mismatch and thus remarkably boost their interaction. We design flatband\r\nresonances
    in a silicon-on-insulator photonic crystal slab to control and enhance the\r\nassociated
    free-electron radiation by tuning their trajectory and velocity. We observe\r\nsignatures
    of flatband enhancement, recording a two-order increase from the\r\nconventional
    diffraction-enabled Smith–Purcell radiation. The enhancement enables\r\npolarization
    shaping of free-electron radiation and characterization of photonic\r\nbands through
    electron-beam measurements. Our results support the use of\r\nflatbands as test
    beds for strong light–electron interaction, particularly relevant for\r\nefficient
    and compact free-electron light sources and accelerators."

  text: 'When impinging on optical structures or passing in their vicinity, free electrons
    can spontaneously emit electromagnetic radiation, a phenomenon generally known
    as cathodoluminescence. Free-electron radiation comes in many guises: Cherenkov,
    transition, and Smith–Purcell radiation, but also electron scintillation, commonly
    referred to as incoherent cathodoluminescence. While those effects have been at
    the heart of many fundamental discoveries and technological developments in high-energy
    physics in the past century, their recent demonstration in photonic and nanophotonic
    systems has attracted a great deal of attention. Those developments arose from
    predictions that exploit nanophotonics for novel radiation regimes, now becoming
    accessible thanks to advances in nanofabrication. In general, the proper design
    of nanophotonic structures can enable shaping, control, and enhancement of free-electron
    radiation, for any of the above-mentioned effects. Free-electron radiation in
    nanophotonics opens the way to promising applications, such as widely tunable
    integrated light sources from x-ray to THz frequencies, miniaturized particle
    accelerators, and highly sensitive high-energy particle detectors. Here, we review
    the emerging field of free-electron radiation in nanophotonics. We first present
    a general, unified framework to describe free-electron light–matter interaction
    in arbitrary nanophotonic systems. We then show how this framework sheds light
    on the physical underpinnings of many methods in the field used to control and
    enhance free-electron radiation. Namely, the framework points to the central role
    played by the photonic eigenmodes in controlling the output properties of free-electron
    radiation (e.g., frequency, directionality, and polarization). We then review
    experimental techniques to characterize free-electron radiation in scanning and
    transmission electron microscopes, which have emerged as the central platforms
    for experimental realization of the phenomena described in this review. We further
    discuss various experimental methods to control and extract spectral, angular,
    and polarization-resolved information on free-electron radiation. We conclude
    this review by outlining novel directions for this field, including ultrafast
    and quantum effects in free-electron radiation, tunable short-wavelength emitters
    in the ultraviolet and soft x-ray regimes, and free-electron radiation from topological
    states in photonic crystals.'

  text: Quantum field theory suggests that electromagnetic fields naturally fluctuate,
    and these fluctuations can be harnessed as a source of perfect randomness. Many
    potential applications of randomness rely on controllable probability distributions.
    We show that vacuum-level bias fields injected into multistable optical systems
    enable a controllable source of quantum randomness, and we demonstrated this concept
    in an optical parametric oscillator (OPO). By injecting bias pulses with less
    than one photon on average, we controlled the probabilities of the two possible
    OPO output states. The potential of our approach for sensing sub–photon-level
    fields was demonstrated by reconstructing the temporal shape of fields below the
    single-photon level. Our results provide a platform to study quantum dynamics
    in nonlinear driven-dissipative systems and point toward applications in probabilistic
    computing and weak field sensing.

  text: 'Converting ionizing radiation into visible light is essential in a wide range
    of fundamental and industrial applications, such as electromagnetic calorimeters
    in high-energy particle detectors, electron detectors, image intensifiers, and
    X-ray imaging. These different areas of technology all rely on scintillators or
    phosphors, i.e., materials that emit light upon bombardment by high-energy particles.
    In all cases, the emission is through spontaneous emission. The fundamental nature
    of spontaneous emission poses limitations on all these technologies, imposing
    an intrinsic trade-off between efficiency and resolution in all imaging applications:
    thicker phosphors are more efficient due to their greater stopping power, which
    however comes at the expense of image blurring due to light spread inside the
    thicker phosphors. Here, the concept of inverse-designed nanophotonic scintillators
    is proposed, which can overcome the trade-off between resolution and efficiency
    by reshaping the intrinsic spontaneous emission. To exemplify the concept, multilayer
    phosphor nanostructures are designed and these nanostructures are compared to
    state-of-the-art phosphor screens in image intensifiers, showing a threefold resolution
    enhancement simultaneous with a threefold efficiency enhancement. The enabling
    concept is applying the ubiquitous Purcell effect for the first time in a new
    context—for improving image resolution. Looking forward, this approach directly
    applies to a wide range of technologies, including X-ray imaging applications.'

  text: We revisit the derivation of the time-dependent Hartree–Fock equation for
    interacting fermions in a regime coupling a mean-field and a semiclassical scaling,
    contributing two comments to the result obtained in 2014 by Benedikter, Porta,
    and Schlein. First, the derivation holds in arbitrary space dimension. Second,
    by using an explicit formula for the unitary implementation of particle-hole transformations,
    we cast the proof in a form similar to the coherent state method of Rodnianski
    and Schlein for bosons.

  text: "We propose a computational design approach for covering a surface with individually
    addressable RGB LEDs, effectively forming a low-resolution surface screen. To
    achieve a low-cost and scalable approach, we propose creating designs from flat
    PCB panels bent in-place along the surface of a 3D printed core. Working with
    standard rigid PCBs enables the use of\r\nestablished PCB manufacturing services,
    allowing the fabrication of designs with several hundred LEDs. \r\nOur approach
    optimizes the PCB geometry for folding, and then jointly optimizes the LED packing,
    circuit and routing, solving a challenging layout problem under strict manufacturing
    requirements. Unlike paper, PCBs cannot bend beyond a certain point without breaking.
    Therefore, we introduce parametric cut patterns acting as hinges, designed to
    allow bending while remaining compact. To tackle the joint optimization of placement,
    circuit and routing, we propose a specialized algorithm that splits the global
    problem into one sub-problem per triangle, which is then individually solved.\r\nOur
    technique generates PCB blueprints in a completely automated way. After being
    fabricated by a PCB manufacturing service, the boards are bent and glued by the
    user onto the 3D printed support. We demonstrate our technique on a range of physical
    models and virtual examples, creating intricate surface light patterns from hundreds
    of LEDs."

  text: The next-generation semiconductors and devices, such as halide perovskites
    and flexible electronics, are extremely sensitive to water, thus demanding highly
    effective protection that not only seals out water in all forms (vapor, droplet,
    and ice), but simultaneously provides mechanical flexibility, durability, transparency,
    and self-cleaning. Although various solid-state encapsulation methods have been
    developed, no strategy is available that can fully meet all the above requirements.
    Here, we report a bioinspired liquid-based encapsulation strategy that offers
    protection from water without sacrificing the operational properties of the encapsulated
    materials. Using halide perovskite as a model system, we show that damage to the
    perovskite from exposure to water is drastically reduced when it is coated by
    a polymer matrix with infused hydrophobic oil. With a combination of experimental
    and simulation studies, we elucidated the fundamental transport mechanisms of
    ultralow water transmission rate that stem from the ability of the infused liquid
    to fill-in and reduce defects in the coating layer, thus eliminating the low-energy
    diffusion pathways, and to cause water molecules to diffuse as clusters, which
    act together as an excellent water permeation barrier. Importantly, the presence
    of the liquid, as the central component in this encapsulation method provides
    a unique possibility of reversing the water transport direction; therefore, the
    lifetime of enclosed water-sensitive materials could be significantly extended
    via replenishing the hydrophobic oils regularly. We show that the liquid encapsulation
    platform presented here has high potential in providing not only water protection
    of the functional device but also flexibility, optical transparency, and self-healing
    of the coating layer, which are critical for a variety of applications, such as
    in perovskite solar cells and bioelectronics.

  text: Aligned liquid crystal polymers are materials of interest for electronic,
    optic, biological and soft robotic applications. The manufacturing and processing
    of these materials have been widely explored with mechanical alignment establishing
    itself as a preferred method due to its ease of use and widespread applicability.
    However, the fundamental chemistry behind the required two‐step polymerization
    for mechanical alignment has limitations in both fabrication and substrate compatibility.
    In this work we introduce a new protection‐deprotection approach utilizing a two‐stage
    Diels–Alder cyclopentadiene‐maleimide step‐growth polymerization to enable mild
    yet efficient, fast, controlled, reproducible and user‐friendly polymerizations,
    broadening the scope of liquid crystal systems. Thorough characterization of the
    films by DSC, DMA, POM and WAXD show the successful synthesis of a uniaxially
    aligned liquid crystal network with thermomechanical actuation abilities.
